2 Claims. (Cl. 81--15) This invention relates to tools particularly of the type used by carpenters or roofers, and in particular a tool for measuring and bending hangers for eave troughs whereby the length of each hanger may be gradually increased or decreased to provide continuous and efiicient drainage of water in roof troughs.

The purpose of this invention is to provide a mechanical device with which each hanger of a trough for carrying water from a roof to a downspout or the like may be bent by hand to an exact dimension as the hanger is installed whereby a trough suspended by hangers may slope with a continuous pitch.

With the conventional method of bending hangers for eave troughs where the hangers are bent with a monkey wrench or hammer with a block for an anvil, the hangers are bent to approximate dimensions before being carried to the roof and because of unexpected irregularities or because mistakes have been made in calculations a trough will have a pocket in which leaves, sand, and other products will accumulate so that the trough will not drain and dry after each storm and, consequently, rust and corrosion take place and eventually cause openings through the trough. With this thought in mind this invention contemplates a bending tool that is adapted to be adjusted after each hanger is bent whereby the length of each hanger may be increased or decreased so that the bottom of the trough is in a straight line with the low end at the downspout.

The object of this invention is, therefore, to provide a tool for bending hangers of eave troughs wherein each hanger is bent to a predetermined dimension.

Another object of the invention is to provide a tool for bending eave trough hangers wherein the hangers are adapted to be bent as used.

A further object of the invention is to provide a tool for bending hangers for supporting eave troughs in which the tool may be carried in the rule pocket of a garment of a carpenter or mechanic.

A still further object of the invention is to provide a tool for bending hangers for eave troughs in which the tool is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies an elongated bar having a longitudinally disposed internally threaded bore with straight slots extended from the sides of the bore and adapted to receive a fiat strip of material and a thumb screw threaded in one end of the bar and adapted to be adjusted to regulate the length of a strip of material extended into the bar.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure l is an elevational view showing a corner of a roof with an eave trough suspended by a hanger from the roof and with the cave trough shown in section.

Figure 2 is a side elevational view of the cave trough hanger bending tool with part of the body portion thereof broken away and with parts shown in section, and show- "ice ing a hanger extended from one end of the tool, the tool and associated parts being shown on an enlarged scale.

Figure 3 is a longitudinal section through the tool taken on line 3--3 of Fig. 2 showing the cave trough hanger in the bent position in broken lines.

Figure 4 is a cross section through the body of the tool taken on line 44 of Fig. 2.

Figure 5 is a similar section taken on line 5-5 of Fig. 2.

Figure 6 is a longitudinal section through the tool, similar to the broken away end of the tool shown in Fig. 2, the opposite end of the tool being broken away, illustrating the use of the tool for bending a hanger of the type having a threaded stem with a hanger for holding a trough secured by lock nuts to the stem.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved eave trough hanger bender of this invention includes an elongated bar 10 providing a body and a screw 11 having a knurled head 12, the screw being threaded into an internally threaded bore 13 and the body being provided with slots 14 and 15 which are positioned to receive edges of a fiat strip 16 with the strip extended through the bore, as shown in Fig. 4.

As illustrated in the drawing the tip of the screw or threaded stem 11 is provided with a pin 17 that is positioned to engage the inner end of the strip 16 whereby in making a plurality of hangers of equal lengths the pin 17 may be set to bend the upper end of the first hanger so that a trough, as indicated by the numeral 18 will be suspended a desired distance from the upper corner 19 of a roof 20 and with the parts set in this position the first hanger is bent with the intermediate portion thereof extended from a point 21 to a point 22. With this distance determined the screw 11 is turned inwardly to shorten the length of the upper end 23 of the hanger whereby the distance between the points 21 and 22 increases with each succeeding hanger.

With the point 19 level, the bottom of the cave trough will slope downwardly in a straight line with the low point at a downspout or the like.

The body of the bar 10 may be rectangular shaped in cross section, as shown in Figs. 4 and 5, or may be made of any suitable shape and the slots 14 and 15 may extend inwardly to the point 24, as shown in Fig. 2, or to any suitable point.

The strap providing the cave trough hanger is preferably, provided with spaced openings 25 and 26 that are positioned to receive nails or other fasteners and the extended end is provided with a loop 27 that may be shaped to correspond with the cross section of a trough.

As illustrated in Fig. 1 the extended end or angularly disposed section 23 of the hangers are secured to the roof 20 with nails 28, or the like.

In the design illustrated in Fig. 6 the tool or body 10 is used for bending a hanger having a threaded stem 29 and, as shown in Fig. 6, the stem 29 is provided with a flat section 30 having openings 31 and 32 therein, the openings being positioned to receive nails or other fasteners for securing the hanger to a roof with the parts as illustrated in Fig. l, and the extended end of the stem is provided with lock nuts 33 and 34 between which the flat portion or strap of a hanger for an cave trough may be secured.

It will be understood, therefore, that the bending tool may be used for hangers and other devices of different types and designs.

It will be understood, that other modifications within the scope of the appended claims. may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

1. A hanger bender comprising an elongated bar having a continuous longitudinally disposed internally threaded bore with aligned slots extended from opposite sides of the bore and adapted to receive a fiat strip of material with said flat strip of material extended through the bore, said slots extended inwardly from one end to a point spaced from the opposite end to limit the insertion of the flat strip of material into said bar, and an elongated threaded stern extended into the end of the bar opposite to that from which the slots extend to engage the end of the flat strip of material to limit the movement of the flat strip of material within the slots.

2. In an eave trough hanger bending tool, the combination which comprises an elongated bar, rectangularshaped in cross section and having a continuous bore extended therethrough, said bar having a threaded section at one end and having aligned slots extended from opposite sides of the bore and positioned to receive a flat strip of material to limit the insertion of the flat strip of material into the bar, and an elongated threaded stem having a pin on one end and a head on the opposite end positioned in the bore and threaded through the threaded section thereof the said pin engaging the inner end of the fiat strip of material to limit the movement of said strip within said slots.
